Latest version of Substance Designer has an updated version of the PBR Render node, and it's great! The quality is much higher, render is physically correct and you have some nice options like DoF and bloom...just to name the few,

While I was writing an article for the Substance website I ran some old assets through it. These are some of the tests I did with my Material Marathon and Heroic game badges.

These are direct screenshots from Substance Designer.
